Uno Hoo!
I agree it is the method of choice and more efficient and less stressful provided that everybody knows the rule and obeys it. Sadly I don't think that UK drivers are disciplined or courteous enough for it to work. It is one of only a handful of situations where the US gets it right.
But if you observe what happens now you get people cutting each other up and having to stop dead stalling both lanes completely for seconds at a time (and sometimes resulting in low speed scrape collisions). It is even worse when you get complete prats driving at speed down the hard shoulder and then trying to force their way out into L1 at the last minute.
The single lane can carry a certain volume of vehicles away, but the every man for himself aggressive cut up and cut in driving style of the UK cannot feed two lanes into one fast enough to keep a 30 or 50 mph single lane fully populated with vehicles. The average speed gets hammered by excessive use of a club foot on the brake and accelerator trying to keep the bad guy from "pushing in". It only becomes a problem in moderately heavy traffic when queues have developed. The transition to turbulent flow is abrupt and damaging to throughput.
A clearly defined use both lanes and merge alternately rule would increase capacity at these choke points.
